Natural Alternatives to Antidepressants: What Actually Has Evidence

## The Honest Landscape Most "natural alternatives to antidepressants" are either weakly evidenced or work only for mild depression. Here's what actually has clinical evidence. ## What Has Real Evidence **Exercise:** The most robustly evidenced natural intervention. A 2016 Cochrane review of 39 trials found exercise produced significant reductions in depression comparable to antidepressants for mild-to-moderate depression. Limitation: requires sustained motivation, which depression directly impairs. **Omega-3 Fatty Acids (EPA):** A 2019 meta-analysis in *Translational Psychiatry* found EPA supplementation produced significant antidepressant effects, particularly in people with elevated inflammatory markers. Effect size is modest. **St. John's Wort:** Effective for mild-to-moderate depression. Critical warning: significantly reduces effectiveness of many medications including birth control and anticoagulants. **Lion's Mane Mushroom:** A 2009 Japanese trial found lion's mane significantly reduced depression and anxiety scores. Mechanism is nerve growth factor (NGF) stimulation. **Psilocybin (Microdosing):** The most robustly evidenced intervention for treatment-resistant depression. Two landmark trials showed significant effects even in patients who had failed multiple prior treatments. ## What Doesn't Have Strong Evidence Magnesium (except for deficiency), vitamin D (except for deficiency), ashwagandha (anxiety yes, depression limited), CBD (anxiety yes, depression limited). ## How to Think About This Natural interventions work best in combination. Exercise + omega-3s + lion's mane + a microdosing protocol is more powerful than any single intervention.
